Economic Operations for a Microgrid Based on Interval Planning Method with Consideration of Electric Vehicle

Large volatility in renewable energies and random loads generated by electric vehicles bring new challenges to the economic operations within microgrid. This paper takes uncertainties of renewable energy sources as well as the random charging behavior of electric vehicles into consideration by using interval planning method. The Monte Carlo method is introduced to formulate the random charging behavior of electric vehicles. Solutions provide an interval planning model for economic operations of the microgrid. A case study is presented to illustrate the proposed strategy, and the influence of load fluctuations and electric vehicle on the operation cost of microgrid is discussed.
